Openstudt what are the coordinates of the turning point for the function f(x) = (x − 2)3 + 1? (−2, −1) (−2, 1) (2, −1) (2, 1)

Dominik [7]

f(x) = (x - 2)^3 + 1

Find the derivative:-

f'(x) = 3(x -2)^2 This = 0 at the turning points:-

so 3(x - 2)^2 =

giving x = 2 . When x = 2 f(x) = 3(2-2)^3 + 1 = 1

Answer is (2, 1)

Michael wants to take French or Spanish, or both. But classes are closed, and he must apply and get accepted to be allowed to en

Brums [2.3K]

Answer:

80%.

Step-by-step explanation:

Given the following probabilities:

P(Micheal Being admitted to French), P(F)=50%
P(Micheal Being admitted to Spanish), P(S)=50%

In Probability Theory, when we have BOTH , we mean the intersection of the probabilities. Therefore:

P(Micheal Being admitted to BOTH French and Spanish), $P(F \cap S)=20\%$

We want to determine the probability that he will be enrolled in either French or Spanish (or possibly both).

Probability of either A OR B = $P(F \cup S)$

From Probability Theory:

$P(F \cup S) = P(F)+P(S)-P(F \cap S)\\P(F \cup S) =50+50-20\\P(F \cup S) =80$

The probability that he will be enrolled in either French or Spanish (or possibly both) is 80%.

Find the distance from the point to the given plane. (−8, 7, 6), x − 2y − 4z = 8

vlabodo [156]

The formula for the distance from a point (x, y, z) to the plane ax +by +cz +d = 0 is this:
.. distance = |ax +by +cz +d|/√(a^2 +b^2 +c^2)

For your point and plane, that is
.. distance = |-8 -2*7 -4*6 -8|/√(1^2 +2^2 +4^2)
.. = 54/√21
.. = (18/7)√21
